Is a Ported 90/90 set-up worth it for FI?????
I guess it is different for everyone. I was pushing 17psi on mine and no problems. I did pick up a victor jr. today though just one less thing to worry about I guess.
FWIW I switched between a FAST 90/90 and the LS6/ported stock throttle body several times and there was no difference either way. Sold it and spent the money on a good set of heads that did make a difference.
But now with bigger heads/cam I'm using sometimes I think of trying the fast again, got to be worth .011 in the 1/4, maybe

i did recall katech doing back to back test in a n/a form engine against a fast 90/90 and they came up with a zero hp or trq gain- dont know why it did not perform
so by having a guess-the sheetmetal would be good for 4 things- 1- looks
2-big cubes 3-big cubes and turbo or turbo's 4. no 3 and a lot of rpms
i was going to pay the 3 k until i found out katech did not get a gain-
so i kept and i am still using my fast 90-if i was really rich i would just buy the wilson one for looks-but i am not-
i am also suprised since i joined this forum that heaps of threads report people getting big hp+torq+ and good et's out of the ls6 intake
so i am very suprised also that the ls6 performs so well in the fi department-
i was also under the impression that a better intake would gain more or perform better than a standard factory item-not in some cases as i have come'ed to understand-
Since you are forcing the air thru it can compensate for not as good flowing heads and intake. But you should be able to make same power at lower boost level with better heads and intake. There are also other reasons to go with different heads and intake. I like the option of direct port on my fast intake.
There have been sizable dyno gains NA on the dyno section especially from ported fast 90 combos.

I'm not trying to discourage anyone from buying or using one, using one certainly cant hurt and if you have the $$ to spend it looks better than a stocker at least..
